Abstract: A reconstructed discontinuous Galerkin method is presented for the solution of the compressible Navier-Stokes equations on arbitrary grids. In this method, an in-cell reconstruction is developed to obtain a higher-order polynomial representation of the underlying discontinuous Galerkin polynomial solution and an inter-cell reconstruction is introduced to obtain a continuous polynomial solution on the union of two neighboring, interface-sharing cells. The developed RDG method is used to compute a variety of flow problems on arbitrary meshes to demonstrate its accuracy, efficiency, and robustness. The numerical results indicate that the in-cell reconstruction DG method is able to obtain a third-order accurate solution at a slightly higher cost than its second-order DG method and significantly increases its performance significantly increases its performance over the third order DG method in terms of computing costs and storage requirements, and the inter-cell reconstruction DG method is a simple alternative for an accurate, stable, consistent, and efficient discretization of the viscous fluxes, and is capable of delivering the same accuracy as BR2 scheme at a quarter of its computing costs.
